$($a$)$ Wil the electric field strength between two paralel

conducting plates exceed the breakdown strength for air $($

$3\mathrm{.}0106$V$/$m$)$ if the plates are separated by $2\mathrm{.}00$ mm and

a potential difference of $5\mathrm{.}0103$V is applied? $($b$)$ How

close together can the plates be with this applied voltage?
